Also, when performing preset adjustment (or manual tuning in some cases), by rotating the manual tuning shaft 24, the bevel gear 25 of the manual tuning shaft 24 and the gear body 1
Since the bevel gear 26 of 1, the tooth portion 13 of the gear body 11, and the gear 9 of the threaded rod 8 are normally in a meshing state (when the tuning shaft 23 is not rotating), the rotation of the manual tuning shaft 24 is caused by the rotation of the gear. body 1
1 to the threaded rod 8, and the slider 14
The memory slug 10 on the threaded rod 8, which is held between both guide members 15 and 15, is moved.

In addition, when the tuning shaft rotates, the gear coupling of the manual tuning system is released, and when the manual tuning shaft rotates, the gear coupling of the detent tuning system is released, so there is no risk that both operation transmission systems will operate at the same time. The operation reliability is high, and even if both the tuning axis and the manual tuning axis are rotated at the same time due to an erroneous operation during detent tuning, the gears of the manual tuning system are disengaged, so the gears will be in the correct position beforehand. There is no fear of disturbing the adjusted preset position.

Overall, the operability and operational reliability are good, and rotary preset tuners are smaller than conventional push-button tuners for vehicles, so they are required to be compact and easy to operate. However, it has great practical utility when applied to car-mounted radio receivers where it is difficult to pay close attention to tuning operations.
